Simplifying w2 + -6w + -5 = 0 Reorder the terms: -5 + -6w + w2 = 0 Solving -5 + -6w + w2 = 0 Solving for variable 'w'. Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + -6w + 5 + w2 = 0 + 5 Reorder the terms: -5 + 5 + -6w + w2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -6w + w2 = 0 + 5 -6w + w2 = 0 + 5 Combine like terms: 0 + 5 = 5 -6w + w2 = 5 The w term is -6w. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6w + 9 + w2 = 5 + 9 Reorder the terms: 9 + -6w + w2 = 5 + 9 Combine like terms: 5 + 9 = 14 9 + -6w + w2 = 14 Factor a perfect square on the left side: (w + -3)(w + -3) = 14 Calculate the square root of the right side: 3.741657387 Break this problem into two subproblems by setting (w + -3) equal to 3.741657387 and -3.741657387.Subproblem 1
w + -3 = 3.741657387 Simplifying w + -3 = 3.741657387 Reorder the terms: -3 + w = 3.741657387 Solving -3 + w = 3.741657387 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = 3.741657387 + 3 Combine like terms: -3 + 3 = 0 0 + w = 3.741657387 + 3 w = 3.741657387 + 3 Combine like terms: 3.741657387 + 3 = 6.741657387 w = 6.741657387 Simplifying w = 6.741657387Subproblem 2
w + -3 = -3.741657387 Simplifying w + -3 = -3.741657387 Reorder the terms: -3 + w = -3.741657387 Solving -3 + w = -3.741657387 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + w = -3.741657387 + 3 Combine like terms: -3 + 3 = 0 0 + w = -3.741657387 + 3 w = -3.741657387 + 3 Combine like terms: -3.741657387 + 3 = -0.741657387 w = -0.741657387 Simplifying w = -0.741657387Solution
The solution to the problem is based on the solutions from the subproblems. w = {6.741657387, -0.741657387}
